Abstract

Background

A new species, Begonia myanmarica, was discovered from Myanmar and herein documented. Characterized by a single developed wing in the ovary/fruit, this species would be assigned to sect. Monopteron (sensu Doorenbos et al. in The sections of Begonia including descriptions, keys and species lists: studies in Begoniaceae VI. Wageningen Agricultural University, Wageningen, 1998) that is known by B. griffithiana and B. nepalensis from the Himalaya. To confirm its sectional assignment, we conducted morphological, phylogenetic and cytological studies.

Results

Morphological observations indicated that B. myanmarica was distinguishable from the two known species of sect. Monopteron by the leaf shape and size, 1-locular ovary, parietal placentation and chromosome number. Molecular phylogenetic analysis using nrITS sequences showed that B. myanmarica was not allied with the clade of sect. Monopteron, though both were nested within sect. Platycentrum-sect. Sphenanthera clade.

Conclusions

Studies of morphology, molecular phylogenetics and cytology support the recognition of the new species, Begonia myanmarica, which is fully described and illustrated. Our results also indicate that B. myanmarica is not closely related to species previously assigned to sect. Monopteron, suggesting that the fruit morphology of a single developed wing in the ovary/fruit characterizing sect. Monopteron is homoplasious.

Hyphessobrycon klausanni

García-Alzate, Urbano-Bonilla & Taphorn, 2017

DOI: 10.3897/zookeys.668.11489

Abstract

Hyphessobrycon klausanni sp. n. is described from small drainages of the upper Guaviare River (Orinoco River Basin) in Colombia. It differs from all congeners by having a wide, conspicuous, dark lateral stripe extending from the anterior margin of the eye across the body and continued through the middle caudal-fin rays, and that covers (vertically) three or four horizontal scale rows. It also differs by having an orange-yellow stripe extending from the anterosuperior margin of the eye to the caudal peduncle above the lateral line in life. It differs from all other species of Hyphessobrycon that have a similar dark lateral stripe: H. cyanotaenia, H. loretoensis, H. melanostichos, H. nigricinctus, H. herbertaxelrodi, H. eschwartzae, H. montogoi, H. psittacus, H. metae, H. margitae, H. vanzolinii, and H. peruvianus in having only three or four pored scales in the lateral line, 21 to 24 lateral scales and six teeth in the inner premaxillary row. Hyphessobrycon klausanni differs from H. loretoensis in having seven to eight maxillary teeth (vs. three to four) and in having a longer caudal peduncle (12.4–17.0% SL vs. 4.6–8.0% SL). Additionally Hyphessobrycon klausanni can be distinguished from the other species of Hyphessobrycon with a dark lateral stripe from the Orinoco River Basin (H. metae and H. acaciae) in having two teeth in the outer premaxillary row (vs. three to four) and 10 branched pectoral–fin rays (vs. 11 to 12). It further differs from H. metae by the length of the snout (17.6–22.8% HL vs. 9.9–15.2% HL) and by the length of the caudal peduncle (12.4–17.0% SL vs. 7.3–11.8% SL).

Keywords: New taxon, Neotropical Ichthyology, Guaviare River, diversity

Figure 3. Live colours of Hyphessobrycon klausanni sp. n. Paratype, UARC–IC 540, 22.4 mm SL.

Etymology: Research leading to the discovery and recognition of this species was partially funded by Mr. Klaus-Peter Lang from Oberhausen, Germany. To commemorate the 80th birthday of his mother, this species is dedicated to and named for his father “Klaus” and his mother “Anni”.

Ecological note: Hyphessobrycon klausanni lives in shallow (0.30–1.5 m) well-oxygenated (6.39–7.68 mg/l) streams with transparent waters flowing (0.063 m/s) over different types of substrates (rocks, sand, gravel and decomposing organic material). The temperature range was narrow, 25.5–26°C but pH varied from moderately acidic to basic (6.47–8.7). Hyphessobrycon klausanni was found near shore among aquatic vegetation, tree roots and fallen logs. Other species found at the sites included: Hemigrammus barrigonae, Ctenobrycon spilurus, Tyttocharax metae, Moenkhausia oligolepis, M. chrysargyrea, M. lepidura, Chrysobrycon guahibo, Ochmacanthus orinoco, Farlowella vittata, Ancistrus triradiatus, Centromochlus reticulatus and Anablepsoides sp. Stomach content analysis (n = 4) revealed a diet of aquatic and terrestrial invertebrates: Coleoptera (Dytiscidae), Ephemeroptera, Hymenoptera (Formicidae), larvae of Chironomidae and others not identified due to the degree of fragmentation.

Resumen: Hyphessobrycon klausanni sp. n. es descrita de pequeños drenajes del alto río Guaviare (cuenca del río Orinoco) en Colombia. Se diferencia de todos los congéneres por tener una amplia franja lateral oscura lateral que se extiende desde el margen anterior del ojo a través del cuerpo y se continúa hasta la base de la aleta caudal y que cubre (verticalmente) tres o cuatro escamas laterales, además difiere por tener una franja de color naranja-amarillo que se extiende desde el margen anterosuperior del ojo hasta el pedúnculo caudal por encima de la línea lateral en vida. Se diferencia de H. cyanotaenia, H. loretoensis, H. melanostichos, H. nigricinctus, H. herbertaxelrodi, H. eschwartzae, H. montogoi, H. psittacus, H. metae, H. margitae, H. vanzolinii, y H. peruvianus por tener solo 3 a 4 escamas con poros en la línea lateral, 21 a 24 escamas laterales y 6 dientes en la fila interna del premaxilar. Hyphessobryconklausanni se diferencia de H. loretoensis por presentar 7 a 8 dientes maxilares (vs. 3 a 4) y la longitud del pedúnculo caudal (12.4–17.0% LE vs. 4.6–8.0% LE). Además se puede distinguir de las demás especies con banda lateral oscura presentes en la cuenca del rio Orinoco (H. metae y H. acaciae) por tener dos dientes en la fila externa del premaxilar (vs. 3 a 4) y 10 radios ramificados en la aleta pectoral (vs. 11 a 12), además se separa de H. metae por la longitud de hocico (17.6–22.8% LC vs. 9.9–15.2% LC) y por la longitud del pedúnculo caudal (12.4–17.0% LE vs. 7.3–11.8% LE).

Disjunctitermes insularis

Scheffrahn, Carrijo, Postle & Tonini, 2017

DOI: 10.3897/zookeys.665.11599

Abstract

Disjunctitermes insularis gen. n. & sp. n. is described from workers collected on Guadeloupe and in Peru and is the first soldierless termite found on a deep-water island. As with many soldierless and soil-feeding termite species, the enteric valve morphology is an essential diagnostic character of D. insularis. The D. insularis sequence cluster, derived from a barcode analysis with twelve other described genera of New World Apicotermitinae, is well resolved. Results of a stochastic dynamic spread model suggest that the occurrence of D. insularis on Guadeloupe may be the result of a pre-Colombian overwater dispersal event from mainland South America.

Disjunctitermes Scheffrahn, gen. n.

Diagnosis: Disjunctitermes is one of the described Neotropical apicotermitines that, along with Anoplotermes banksi, A. pacificus, and Hydrecotermes spp., possess strongly inflated fore tibia and lack spiny sclerotized enteric valves. Disjunctitermes is closest to A. banksi, but can be distinguished from the latter by the subsidiary tooth on the left mandible, the larger EV seating and the more truncate terminus of P2 (Fig. 3C, D). Hydrecotermes lacks a spheroidal mesenteric tongue.

Etymology: The genus name is derived from its current, widely disjunct distribution on Guadeloupe and Peru.

Disjunctitermes insularis Scheffrahn, sp. n.

Diagnosis: See also comparison for Disjunctitermes above. The EV pads of D. insularis differ from those of the four other described species with unarmed EV as follows (Fig. 3): each pad of A. banksi is vase-shaped, with a narrow posterior end that widens into an oval base reminiscent of an orb-weaving spider web (Fig. 3C); the A. pacificus pads are shaped similarly to those of A. banksi but are less concentric and are adorned with a few unsclerotized spines (Fig. 3E); while the pads of H. arienesho and H. kawaii are ovoid in shape (Figs 3F and 3G, respectively).

Etymology: The species name is derived from its unexpected island locality.

Habitat and biology: Workers were collected in foraging groups under rocks and stones in rainforest habitats. Like many New World Apicotermitinae, D. insularis does not build any above-ground structures. Mature worker gut contents confirm that they feed on the organic fraction of soil.

Cnemaspis kandambyi

Batuwita& Udugampala, 2017

DOI: 10.11646/zootaxa.4254.1.4

Abstract

A new species of Cnemaspis Strauch is described from Knuckles Range of Sri Lanka. This new species had been previously confused with Cnemaspis podihuna Deraniyagala. Cnemaspis kandambyi sp. nov. closely resembles C. podihuna and C. molligodai Wickramasinghe & Munindradasa. Cnemaspis kandambyi sp. nov. differs from C. podihuna by having 7–8 (versus 3–6) unpored scales in each side of the precloacal-femoral pores row, lacking (versus having) an internasal scale, body (axilla to groin) relatively long 47.7–48.3 (versus 38.1–38.7)% of SVL and dorsum dark brown (versus bright yellow). Cnemaspis kandambyi sp. nov. also distinguished from C. molligodai by having 4 (versus 5) precloacal pores, 5–6 (versus 7–9) femoral pores on each side, precloacal pores not in an inverted V-shaped arrangement (versus in inverted V-shaped arrangement), lacking (versus having) a distinct black marking on nape and a black lateral stripe begins behind eye extends laterally beyond the origin of forearm (versus not extending beyond the origin of forearm). Additionally, Cnemaspis kandambyi sp. nov. and C. molligodai show discrete distribution: former restricted to Knuckles Range and the latter confined to Lowland wet zone of Sri Lanka. We confirm that, no type material of Cnemaspis podihuna survive in the current collection of the National Museum of Sri Lanka.

Nettorhamphos radula

Conway, Moore & Summers, 2017

Washington.edu DOI: 10.1643/CI-16-560

Nettorhamphos radula, new genus and species, is described from two specimens, 20.3–40.2 mm SL, trawled from sponge and algae reefs between 30–40 meters in depth offshore from Fremantle, Western Australia. The new taxon is distinguished from all other members of the Gobiesocidae by having vast fields of tiny conical teeth throughout the oral jaws that are arranged in multiple, regular rows along the lingual surface of the premaxilla and the dentary. The new taxon is tentatively considered a close relative of two other southern Australian endemic clingfish taxa (Posidonichthys and the undescribed “Genus A”) based on the presence of a well-developed and heavily ossified subopercular bone that articulates strongly with both the opercle (dorsally) and the preopercle (anteriorly).

Nettorhamphos, new genus

Type species.— Nettorhamphos radula, new species

Etymology.— A combination of the Greek words (netta), meaning duck, and (rhamphos), meaning bill, curved-beak. Gender neuter.

Nettorhamphos radula, new species

Common name: Duckbilled Clingfish

Distribution and habitat.— Known to date only from two locations to the west of Five Fathom Bank (Indian Ocean), off the coast of Fremantle, Western Australia (Fig. 11). The new species was collected via trawls through algae/sponge reefs between 33–37 meters in depth. Other species of fishes collected by the same trawls include the pipefish Stigmatopora nigra, the labrids Austrolabrus maculatus, Eupetrichthys angustipes,Siphonognathus caninus, and S. attenuatus, and the gobiesocids Alabes occidentalis and ‘‘Genus A sp. 2’’ (sensu Hutchins, 2008).

Etymology.— From the Latin radula, a tool used for scraping. In reference to the many tiny conical teeth on the lingual surface of the premaxilla and dentary, which are reminiscent of the radula of a snail. A noun in apposition.

ABSTRACT

Plesiosauria is a diverse clade of marine reptiles that have been studied since the early 19th century. However, phylogenetic relationships within the group have been contentious due to limited taxon sampling and a misunderstanding of how ontogeny and interspecific and intraspecific variation affect character states. This is particularly true for elasmosaurids, a Cretaceous clade of long-necked plesiosaurians. In 2010, a new, nearly complete skeleton, MOR 3072, was collected from the Late Cretaceous (Campanian–Maastrichtian) Bearpaw Shale of northeast Montana. The specimen provides detailed morphological information rarely observed within Elasmosauridae, including a complete skull, the anterior 23 cervical vertebrae, a partial dorsal and caudal vertebral column, incomplete pectoral and pelvic girdles, elements of both fore- and hind limbs, ribs, and gastralia. Being early Maastrichtian in age, MOR 3072 is the stratigraphically youngest elasmosaurid known from the Western Interior Seaway and is recognized as a new genus and species, Nakonanectes bradti. We present a description of Nakonanectes bradti and conduct an extended phylogenetic analysis of Elasmosauridae. N. bradti is found to be deeply nested within the clade of large-bodied, long-necked, Western Interior Styxosaurinae. However, MOR 3072 is one of the smallest adult elasmosaurids ever recovered (5.1–5.6 m) and exhibits a reduced neck length compared with other North American elasmosaurids, resulting from a reduction in both centrum length and number of cervical vertebrae (39–42 were originally present). These features are convergent with the Southern Hemisphere clade of short-necked Maastrichtian elasmosaurids, Aristonectinae, and demonstrate multiple origins of short-necked body proportions from longer-necked ancestors within Elasmosauridae.

The newly named short-necked elasmosaur, Nakonanectes bradti, swims through an ancient sea in this artist’s reconstruction.

Piscivorenantiornis inusitatus

Wang & Zhou, 2017

DOI: 10.1080/02724634.2017.1278702

ABSTRACT

A fish-eating enantiornithine bird with a gastric pellet composed of fish bones has recently been reported from the Lower Cretaceous Jiufotang Formation of Liaoning Province, northeastern China. Along with other discoveries, this specimen reveals that distinct features of modern avian digestive system were well established in those early birds. On the basis of a detailed anatomical study presented here, we show that this fish-eating enantiornithine bird represents a new taxon, Piscivorenantiornis inusitatus, gen. et sp. nov. The well-preserved elements of the skull, neck, sternum, and pelvis further enrich our understanding of the morphological diversity in early enantiornithines. Most notably, the cranial articular facet of the caudal cervical vertebra is dorsoventrally concave and mediolaterally convex, a feature otherwise unknown among other birds and with unclear functional significance.

Tometes siderocarajensis

Andrade, Machado, Jégu, Farias & Giarrizzo, 2017

DOI: 10.1371/journal.pone.0170053

Abstract

A new large serrasalmid species of Tometes is described from the Tocantins-Araguaia River Basin. Tometes siderocarajensis sp. nov. is currently found in the rapids of the Itacaiúnas River Basin, and formerly inhabited the lower Tocantins River. The new species can be distinguished from all congeners, except from T. ancylorhynchus, by the presence of lateral space between 1st and 2nd premaxillary teeth, and by the absence of lateral cusps in these two teeth. However, T. siderocarajensis sp. nov. can be differentiated from syntopic congener T. ancylorhynchus by an entirely black with mottled red body in live specimens, densely pigmented pelvic fins with a high concentration of dark chromatophores, and the presence of 39 to 41 rows of circumpeduncular scales (vs. silvery body coloration with slightly reddish overtones on middle flank during breeding period in live specimens, hyaline to slightly pale coloration on distalmost region of pelvic fins, and 30 to 36 rows of circumpeduncular scales). Additionally, molecular sequence shows that T. siderocarajensis sp. nov. is reciprocally monophyletic, and diagnosable from all congeners by having two autapomorphic molecular characters in the mitochondrial gene COI. The phylogenetic reconstruction still show that T. siderocarajensis sp. nov. is closely related to T. trilobatus. This is the first molecular study using an integrative taxonomic approach based on morphological and molecular sequence data for all described species of Tometes. These findings increase the number of formally described species of Tometes to seven. A key to the Tometes species is provided.

(b) ZUEC 12598, female, 328.0 mm SL. Preserved specimens.

Diagnosis: Tometes siderocarajensis sp. nov. is distinguished from all congeners by dense pigmentation on the distalmost portion of the pelvic-fin rays or the entirety of the fin (Fig 2A, Fig 2B)[vs. pelvic fin hyaline or pale, or with few scattered dark chromatophores along distal portion of rays (Fig 2C, Fig 2E)]. Additionally, it is distinguished from all, except from T. camunani and T. kranponhah, by having more circumpeduncular scale rows (39‒41 vs. 38 or less), and from T. kranponhah and T. trilobatus by having 1st and 2nd labial premaxillary teeth laterally spaced (Fig 3A) (vs. 1st and 2nd labial premaxillary teeth with lateral contact). The new species is further distinguished from T. trilobatus by having more perforated lateral line scales (74–84 vs. 58–72) and from T. makue by having more spines on ventral keel (11–17 prepelvic spines and 26–33 total spines vs. 0–9 and 10–23, respectively). Finally, Tometes siderocarajensis sp. nov. can be distinguished from T. lebaili by having a terminal to gently upturned mouth and invariably 5 dentary teeth (vs. a markedly upturned mouth and 6–7 dentary teeth).

Fig 7. Itacaiúnas River, Pará State, at Mosaic of Conservation Units of Serra dos Carajás, type locality of Tometes siderocarajensis.

Etymology: The epithet siderocarajensis alludes to the locality ‘Serra and Carajás’, which is the largest high-grade iron deposit in the world. From the Greek‒Latin sidero means ‘iron’, and carajensis in allusion to the type locality. A toponymic adjective.

Geographic distribution: Tometes siderocarajensis is known to occur in the rapids of the Itacaiúnas River (Fig 7) and in its right-bank tributary, the Cateté River (average elevation of localities around 220 m a.s.l.), both located in the Mosaic of Conservation Units of Serra dos Carajás, Tocantins-Araguaia River Basin, State of Pará (Fig 8). In addition, T. siderocarajensis had its record confirmed in the Tocantins River based on specimens collected before the construction of the Tucuruí Hydroelectric Reservoir (INPA 52481), an area formerly known to contain many rapids but is currently flooded by the dam.

Flagelligorgia gracilis

Cairns & Cordeiro, 2017

DOI: 10.3897/zookeys.668.12203

Abstract

A new genus and species of unbranched golden coral, Flagelligorgia gracilis, is described based on several specimens collected off the southeastern coast of the United States. The genus is provisionally included in the family Chrysogorgiidae, pending molecular confirmation. Flagelligorgia morphologically resembles other unbranched chrysogorgiids, such as Distichogorgia, Chalcogorgia, Helicogorgia and Radicipes, to which it is compared. The type species is illustrated and its distribution mapped.

Keywords: Flagelligorgia gracilis, unbranched octocoral, biserial polyp arrangement, Radicipes, southeastern USA

Scale bars: A: 10 mm, B: 5 mm, C, E: 0.1 mm, D: 0.01.

Taxonomy

Subclass Octocorallia Haeckel, 1866

Order Alcyonacea Lamouroux, 1812
Suborder Calcaxonia Grasshoff, 1999

Family Chrysogorgiidae Verrill, 1883

Type genus: Chrysogorgia Duchassaing & Michelotti, 1864.

Diagnosis: (after Cairns (2001) and Pante et al. (2012)). Calcaxonians having an unjointed, solid (non-spicular), concentrically layered scleroproteinous axis. The axial layers are usually smooth (not undulated) and thus not longitudinally grooved externally; the axis usually displays metallic or iridescent reflections. The colony may be branched or unbranched (flagelliform), arising from a root-like or discoidal, strongly calcified holdfast. Polyps are contractile but not retractile, arranged in rows (uniserial, biserial or multiserial), but never in whorls. Sclerites predominantly flat, smooth scales, in some species warty rods and spindles.

Flagelligorgia gen. n.

Type species: Flagelligorgia gracilis, here designated. Gender: feminine.

Diagnosis: Colonies unbranched (flagelliform), loosely coiled, attached by a holdfast; axis composed of undulating concentric layers (Figs 1C–E, 2D). Polyps arranged biserially. Body wall and coenenchymal scales elongate, smooth scales. Polyps lack an operculum.

Distribution: Off Southeastern United States from North Carolina to Florida, 196–567 m depths.

Etymology: The name is a combination of flagellum (Latin for small whip) and gorgia (a common octocoral suffix and once the name of the order Gorgonacea, the name derived from the mythical female monster, the Gorgon), in reference to the flagelliform nature of the colony.

Flagelligorgia gracilis sp. n.

Distribution: Southeastern coast of United States from off Outer Banks, North Carolina to off Carysfort Reef (near Key Largo, Florida) (Fig. 4), 196–567 m depths.

Etymology: Named gracilis (Latin for slender, gracile), in allusion to the very slender aspect of the colony.

Gracixalus carinensis was originally described from Myanmar, but samples of the species reported in molecular phylogenetic works were all from Vietnam, far apart from the type locality. Moreover, the voucher specimens used for sequencing seem to have never been critically studied. We newly sequenced specimens from Vietnam and also closely examined morphology of vouchers. As a result, we confirmed that samples treated under this name from Vietnam constitute a single species. Although no molecular data are available for topotypic samples from Myanmar, detailed morphological comparisons revealed that samples from Vietnam are constantly separated from the topotypic samples of G. carinensis by much poorly developed toe webbing. We thus consider the Vietnamese samples as an undescribed species and describe them as Gracixalus sapaensis sp. nov.

Etymology. The specific epithet is derived from Sa Pa, a district in Lao Cai Province, northern Vietnam, where the new species occurs.

Range. Known only from northwestern Vietnam (fig. 5): Lai Chau, Lao Cai and Dak Lak (Nguyen et al., 2009, as Aquixalus). The known localities vary from 1250-2340 m in altitude.

Natural history. Ohler et al. (2000) reported the new species to occur at all the vegetation types they classified (agriculture, scrub, submontane forest, and montane forest) from 1260-2020 m a.s.l. on Fan Si Pan mountains. Specimens were usually found sitting on leaves, rarely branches, up to 2 m from the ground, in the vicinity of mountain streams (median distance observed 3 m). They also reported the new species (as Philautus carinensis) to breed mainly in October-November unlike Ph. odontotarsus (now Kurixalus), and Ph. jinxiuensis and Ph. gracilipes (both now Gracixalus) that breed in July.

Speolabeo musaei (Kottelat & Steiner, 2011)

photo: H. Steiner DOI: 10.11646/zootaxa.4254.4.6

Abstract

Speolabeo, new genus, is established for Bangana musaei, a fish from caves in the Khammouan Karst in Laos. It was originally tentatively placed in the genus Bangana s.l. Besides characters related to hypogean life (absence of eyes, absence of pigment resulting in a whitish body), it is distinguished from all species of Bangana s.l. in having only 7–8½ branched dorsal-fin rays, the pelvic-fin at the vertical between the first unbranched and first branched dorsal-fin rays, and details of mouth morphology.

[2011] Bangana musaei, new species, is described from caves in the Xe Bangfai drainage (a tributary of the Mekong) in central Laos. It is distinguished from all other species of the genus Bangana by its whitish body and absence of eyes. Incisilabeo (type species Labeo behri) is revalidated.

Abstract

Four new specimens of Anchiornis huxleyi (PKUP V1068, BMNHC PH804, BMNHC PH822, and BMNHC PH823) were recently recovered from the late Jurassic fossil beds of the Tiaojishan Formation in northeastern China. These new specimens are almost completely preserved with cranial and postcranial skeletons. Morphological features of Anchiornis huxleyi have implications for paravian character evolution and provide insights into the relationships of major paravian lineages. Anchiornis huxleyi shares derived features with avialans, such as a straight nasal process of the premaxilla and the absence of an external mandibular fenestra in lateral view. However, Anchiornis huxleyi lacks several derived deinonychosaurian features, including a laterally exposed splenial and a specialized raptorial pedal digit II. Morphological comparisons strongly suggest Anchiornis is more closely related to avialans than to deinonychosaurians or troodontids. Anchiornis huxleyi exhibits many conservative paravian features, and closely resembles Archaeopteryx and other Jurassic paravians from Jianchang County, such as Xiaotingia and Eosinopteryx. The other Jianchang paravian, Aurornis xui, is likely a junior synonym of Anchiornishuxleyi.

Merostenus (Merostenus) congoensis

Gibson, 2017

DOI: 10.11646/zootaxa.4255.1.1

Abstract

Reikosiella Yoshimoto, 1969 is synonymized under MerostenusWalker, 1837n. syn. and treated as M. (Reikosiella), one of four subgenera recognized in the genus. Hirticauda Bouček, 1988, previously treated as a subgenus of Reikosiella, is synonymized under M. (Merostenus) n. syn., and two subgenera established in Reikosiella by Gibson (1995) are synonymized under Merostenus and treated as the subgenera M. (Capreocauda) and M. (Incohata) n. syns. The new generic synonymy is proposed after morphological comparison of females and males of Merostenus and Reikosiellasensu Gibson (1995), including reanalysis of features possessed by a basal group of genera of Eupelminae whose females share two hypothesized symplesiomorphies—a medially divided mesotrochantinal plate and lack of a mesotibial apical groove. A checklist of the 51 world species assigned to Merostenus is given, with 1 described species in M. (Incohata), 6 in M. (Capreocauda), 6 in M. (Reikosiella) and 38 in M. (Merostenus). All but one, the type species of Merostenus, represent new combinations. The species of Merostenus with brachypterous females are revised, with 8 of 10 species described as new. In addition to M. (Merostenus) excavatus (Dalman) (♀, ♂) from the Palaearctic, described in the same subgenus are one new species from Mexico, Merostenus (Merostenus) mexicanus n. sp. (♀), and seven from the Afrotropical region, Merostenus (Merostenus) distigma n. sp. (♀: Kenya, Tanzania), Merostenus (Merostenus) micropterus n. sp. (♀: Democratic Republic of the Congo), Merostenus (Merostenus) platyscapus n. sp. (♀: South Africa), Merostenus (Merostenus) reticulatus n. sp. (♀, ♂: Kenya), Merostenus (Merostenus) speculum n. sp. (♀: Burundi), Merostenus (Merostenus) congoensis n. sp. (♀: Democratic Republic of the Congo), and Merostenus (Merostenus) longistylus n. sp. (♀, ♂: South Africa). The first seven species are assigned to the excavatus species-group of M. (Merostenus) based on females sharing a completely sclerotized pronotum and apically truncate syntergum. Also treated is M. (Reikosiella) melinus (Yoshimoto)n. comb. (♀: Argentina, Brazil, Hawaii), the only species known with macropterous to variably strongly brachypterous females. Six species are transferred to other genera. Merostenus ferrugineusYoshimoto & Ishii is transferred to Anastatus Motschulsky as A. ferrugineus(Yoshimoto & Ishii)n. comb., Merostenus guamensisYoshimoto & Ishii and Merostenus palauensis Yoshimoto & Ishii are transferred to Eupelmus Dalman and provisionally classified in E. (Eupelmus) as E. (Eupelmus) guamensis (Yoshimoto & Ishii) n. comb. and E. (Eupelmus) palauensis (Yoshimoto & Ishii) n. comb., Eupelminus subapterus Ashmead is transferred to E. (Eupelmus) as E. (Eupelmus) subapterus (Ashmead) n. comb., and Eupelminus robustus Brues and Eupelminus tarsatus Waterston are transferred to Arachnophaga (Parasolindenia Brues) as Arachnophaga (Parasolindenia) robusta(Brues) n. comb. and Arachnophaga (Parasolindenia) tarsata(Waterston) n. comb. The character-state analysis and treated species are illustrated through macrophotography and, except for A. robusta, notes and illustrations provided for the excluded species to assist their future recognition.

Dioscorea irodensis Wilkin, Rajaonah & Randriamb.

DOI: 10.1007/s12225-017-9677-6

Summary

Morphological character data are used to show that a distinct morphotype of Dioscorea L. from the Irodo valley (East of Sadjoavato) in Antsiranana Province of Madagascar is an undescribed species, differing in its leaf arrangement, pubescence form and male inflorescence structure from all other taxa. It is described as Dioscorea irodensis Wilkin, Rajaonah & Randriamb., illustrated and a distribution map and ecological information provided. It is known from three sites, but is likely to have been eradicated from one of them. The population that has been studied in the field contains a very low number of adult plants. Tubers have been extracted for use as food at a level that appears to be unsustainable. Thus its provisional IUCN conservation status assessment is that it is critically endangered (CR). Its vernacular name in Irodo is Bemandry.

Dioscorea irodensis Wilkin, Rajaonah & Randriamb., sp. nov.

Type: Madagascar, Antsiranana: Diana, Antsiranana II, Anivorano, Irodo, ala fady S of village towards Irodo river estuary, 12°39'6.3"S 49°31'38.2"E, ♀ fr. 8 Feb. 2015, P. Wilkin, J. A. Kennerley, F. Rakotonasolo, M. Hamido & M. Tsaratiana 1675 (holotype TAN!; isotype K!).

Recognition. Tuber horizontal in soil with a curved apex (derived from digging up two plants and inferring a similar position in others from the shape of extraction holes and the Malagasy vernacular name). Leaves in clusters of up to 7 on short herbaceous branches, clustered particularly towards bases of main vegetative stems (Fig. 1A, 2B), blades thin in texture, densely pubescent below and when immature but coarse and never forming a tomentum as in Dioscoreaovinala. Plants at the locality near Irodo represented by Wilkin et al. 1674 and 1675 often have white spotting on their leaf blades which has the appearance of pathogenic infection (see Fig. 2A). Male inflorescences (Fig. 1 E, F) with irregularly spaced, spirally arranged dense cymules of 2 – 8 pedicellate flowers or rarely solitary, vs flowers (sub)sessile, or rarely with a pedicel to 0.5 mm long and solitary or in groups of 2 – 4 (D. ovinala). Fruit not inflated and fleshy during development but thin-lobed and capsular throughout, single layered at dehiscence. Restricted to a small area East of Sadjoavato in Antsiranana Province.

Distribution and habitat. Endemic to the Irodo river Valley and Sahafary forest in Antsiranana Province (Map 1) at altitudes from 30 – 230 m. It is possible that the three collections from South of the village of Irodo represent two subpopulations on either side of the river as opposed to two distinct populations (the term population is used here in an ecological sense, except in the Conservation Status section), but the specimen from Sahafary forest is spatially isolated. At Irodo, it is found in semi-deciduous forest with a canopy to 10 m and a clear shrub layer, the principal canopy trees being Colvillea and Tamarindus, with Pachypodium in the shrub layer. Soil a brown sandy loam, possibly alluvial, or red sand over limestone bedrock. The Sahafary Forest specimen states that it was from scrub forest on red sand.

Etymology. Named for the village of Irodo and the IrodoRiver valley where this species is found.

Vernacular name. Bemandry in the village of Irodo. This name appears to be applied particularly to species with horizontal tubers, for example the element of Dioscoreasoso Jum. & H. Perrier sensulato with the same tuber habit.

Uses. Tuber edible cooked. Rather watery following cooking and thus not fully satisfying the appetite. Dioscoreamaciba, known as batatala in Irodo, is the more sought after species of the two that are found in the Irodo valley and surrounding areas. Not believed to be sold in markets but consumed usually in March/April.

DOI: 10.6620/ZS.2017.56-08

Microphysogobio zhangi n. sp., a new cyprinid species is described from Guangxi Province, China. Morphological and molecular evidence based on mitochondrial DNA Cytochrome b (Cyt b) sequence were used for comparing this new species and other related species. The phylogenetic tree topology revealed that this new species is closely related to M. elongatus and M. fukiensis. We also observed the existence of a peculiar trans-river gene flow in the Pearl River and the Yangtze River populations, and speculated that it was caused by an ancient artificial canal, the Lingqu Canal, which forming a pathway directly connecting these two rivers.

Key words: Taxonomy, Gudgeon, Cytochrome b, Freshwater Fish, Pearl River.

Fangfangia spinicleithralis

Britz, Kottelat & Tan, 2011

Fangfangia spinicleithralis, new genus, new species, is described from peat swamp forest habitats in Kalimantan Tengah, Borneo, Indonesia. It differs from all other cyprinids in having the anteroventral tip of the left cleithrum projecting into a strong anteriorly directed spine and a pointed posteriorly directed spine at the posteroventral aspect of each cleithrum. In addition, it can be diagnosed by the following characters: the base of the dorsal hemitrich of the first pectoral-fin ray with serrated margin, multicuspid pharyngeal teeth, ventrally directed lateral processes on vertebra 1, the high number of procurrent caudal-fin rays (14-18 dorsally, 11-15 ventrally), absence of scales with the exception of six or seven tubular lateral line ossicles, and the greatly elongated middle radials in the anal fin, which may reach half the length of proximal radials.

Fangfangia, new genus

Etymology. The new genus is named after the late Fang Fang, a passionate and productive cypriniform researcher, who left us too early, honouring her contribution to danionine taxonomy and phylogeny. Gender feminine.

Fangfangia spinicleithralis, new species

Distribution.Fangfangia spinicleithralis is presently known only from the type locality in Sebangau peat swamp forest, Kalimantan Tengah, Borneo, Indonesia.

Etymology. The species name spinicleithralis, an adjective, is derived from the Latin words spina, thorn, and cleithralis, belonging to the cleithrum(the main element of the dermal shoulder girdle). It refers to the unique pointed anterior and posterior spines on the cleithrum of this species.
